SAMUEL BINKLEY, OF DUBLIN, INDIANA.

IMPROVEMENT IN GRAIN-DILLS.

Specification forming part of Letters Patent No. 21,736, dated October 12, 1858.

To all whom 'it may concern:

Be it known that I, SAMUEL BINKLEY, of Dublin,Waynecounty, Indiana, have invented a new and useful Improvement in Seeding- Machines; and I hereby declare the following to be a full and exact description ofthe same, reference being had to the accom panying drawings, making part of this specification.

This invention relates to that class of machines in which the seed is delivered from apertures at the bottom of the hopper by means of a perforated reciprocating slide; and it consists in an arrangement to insure the delivery ofthe grain uniformly and without injury.

In the accompanying drawings, Figure l is a transverse section ot' the hopper and its accessories through one of the seed-apertures. Fig. 2 is a detached perspective view of one ofthe staples and a portion ofthe slide.

A represents a hopper, having common apertures a in its bottom.

B is the slide, perforated to correspond with the apertures a in the bottom of the hopper. Each aperture in the slide is bisected by a thin bar, b, the bottom of which is on a level with the lower surface of the slide.

c are a number of spurs extending upward from the bar b to a level with the top of the slide.

d' d are angular protuberances from the sides of the slide-apertures.

E is the staple which contines the slide to the bottom of the hopper. This staple is provided Vit to the drill-tooth.

with grooves e, which leaveintervals between the slide and staple immediately beneath the spaces between the protuberances d on the former, whereas the said protuberances `themselves are in close contact with the staple.

rlhe following is the manner in which the various parts, arranged as explained, operate to deliver the grain equally and without cutting or bruising: As the slide reciprocates to and fro the angular protuberances d agitate the mass of grain and crowd it into the groove-s in the staple, from whence it is delivered into tubes or spouts of customary form to convey The bar b and spurs c, projecting therefrom, are of great service in keeping the mass of grain free and open, and preventing bunching and arching, while the corrugated or grooved form ot' the staple E and the inclined sides of the protuberances d, acting in conjunction therewith, e'ectually prevent all danger of cutting or bruising the grain.

I claim as new and of my invention herein- The slide B, in the described combination, with the grooved or corrugated staple E, for the purposes set forth.

In testimony of which invention I hereunto set my hand.
